I might hang on to the old unit until next weekend and check the display on that, before returning it (unless someone can confirm that really is normal)
So, at the weekend I temporarily re-connected the old stereo (hadn't sent it back yet) and can definitely confirm that the visual display did used to respond to audio levels, but it only did so at relatively high volume (no display at low volume)
Seems like the fix for the audio cutting out at low volume was to fake a signal into the DSP so that it thinks the level is higher than it really is, in order to prevent it cutting out.
Obviously a complete hack of a fix, and just working around the original issue rather than really fixing the root cause issue. Not sure of the hack is in software or hardware tho.
(I'd like to get hold of schematics and source code for this unit, since I'm a software engineer but also with an electronics degree, so pretty sure I could come up with a better fix: however I suspect there's little chance of getting access to those ... our that I'd have the time to do it)
Still, pretty annoying and distracting that the display just constantly flickers now
